MR-J3-_T_
(DIO command/Serial communication operation)
The electronic gear is used to make adjustment
so that the servo amplifier setting matches the
machine moving distance. Also, changing the
electronic gear value allows the machine to be
moved at any multiplication ratio to the moving
distance using the servo amplifier.
[Pr. PA06]/[Pr. PA07]
Automatically adjusts the gain to optimum value if
load applied to the servo motor shaft varies.
Acceleration/deceleration can be made smoothly.
[Pr. PC13]
Used when the built-in regenerative resistor of the
servo amplifier does not have sufficient
regenerative capability for the regenerative power
generated.
Used when the regenerative option cannot
provide enough regenerative power.
Can be used with the servo amplifier of 5kW or
more.
Used when the regenerative option cannot
provide enough regenerative power.
Can be used with the servo amplifier of 5kW or
more.
Alarm history is cleared. [Pr. PC18]
Input devices such as servo-on (SON) can be
assigned to certain pins of the CN6 connector
(MR-J3-_T_) and the CN10 connector (MR-J3-
D01).
[Pr. PD06] to [Pr. PD08], [Pr. Po02] to [Pr. Po07]
Output devices such as Malfunction (ALM) and
Dynamic brake interlock (DB) can be assigned to
certain pins of the CN6 connector (MR-J3-_T_)
and the CN10 connector (MR-J3-D01).
[Pr. PD09] to [Pr. PD11], [Pr. Po08]/[Pr. Po09]
Servo motor torque can be limited to any value.
Limits the servo motor speed with analog inputs
from MR-J3-D01.
A value can be changed from 0% to 200% for a
set speed.
Output signal can be forced on/off independently
of the servo status.
Use this function for output signal wiring check,
etc.
JOG operation positioning operation DO forced
output.
In the test operation mode, a parameter unit or
Setup software (SETUP221E) is required.
The servo motor travel region can be limited using
the forward rotation stroke end (LSP)/reverse
rotation stroke end (LSN).
The travel region is limited using parameters in
terms of address.
The function similar to that of a limit switch is
limited by parameter.
Position commands can be multiplied by 1/864 to
33935. Select "J3 electronic gear setting value
compatibility mode" with [Pr. PA21]. [Pr. PA06]/
[Pr. PA07]
Automatically adjusts the gain to optimum value if
load applied to the servo motor shaft varies.
This enables to start/stop the servo motor
smoothly.
Used when the built-in regenerative resistor of the
servo amplifier does not have sufficient
regenerative capability for the regenerative power
generated.
Used when the regenerative option cannot
provide enough regenerative power.
Can be used with the servo amplifier of 5kW or
more.
Used when the regenerative option cannot

ST1 (Forward rotation start), ST2 (Reverse
rotation start), SON (Servoon), and other input
device can be assigned to any pins of the CN1
connector of MR-J4-_A_-RJ.

The output devices including MBR
(Electromagnetic brake interlock) can be assigned
to certain pins of the CN1 connector of MR-J4-
_A_-RJ.
[Pr. PD23] to [Pr. PD26]/[Pr. PD28]/[Pr. PD47]
Servo motor torque can be limited to any value.
[Pr. PA11]/[Pr. PA12]
Limits the servo motor speed with analog inputs
from MR-J4-_A_-RJ. (However, the analog inputs
of MR-J4-_A_-RJ and MR-D01 are mutually
exclusive.)
A value can be changed from 0% to 200% for a
set speed.
Output signal can be forced on/off independently
of the servo status.
Use this function for checking output signal wiring,
etc.

However, MR Configurator2 is necessary for
positioning operation, program operation, and
single-step feed.
Limits travel intervals using LSP (Forward rotation
stroke end) and LSN
(Reverse rotation stroke end).
Limits travel intervals by address using
parameters.
Enables the same function with the limit switch by
setting parameters.
